Fix locations of unattributed statements

Browse Source 
The `statement` and null-statement rules start with an optional attribute
list. When it is empty, the reduced location starts at the previous token
instead of the statement. Diagnostics using that location can consequently
point to the beginning of the source file.

Use the statement or semicolon location when no attributes are present.
